Bello-Ochende, Tunde; Meyer, Josua P.; Ighalo, Fervent U. (Taylor & Francis, 2010-12)This study deals with the geometric optimization of a silicon based micro-channel heat sink using a combined numerical optimization and constructal theory. The objective is to minimize the wall peak temperature subject ...

Olakoyejo, O.T. (Olabode Thomas); Bello-Ochende, Tunde; Meyer, Josua P. (Elsevier, 2012-07)This paper presents a geometric optimisation of conjugate cooling channels in forced convection with internal heat generation. Two configurations were studied; circular channels and square channels. The configurations ...

Page, L.G. (Logan Garrick); Bello-Ochende, Tunde; Meyer, Josua P. (Elsevier, 2013-01)This paper investigated the thermal behaviour of an assembly of multi scale cylinders in a staggered counter-rotating configuration cooled by natural convection with the objective of maximizing the heat transfer density ...
-
Bello-Ochende, Tunde; Meyer, Josua P.; Bejan, A. (Elsevier, 2010-06)In this paper we use constructal theory to determine the configuration of two rows of pin–fins so that the total heat transfer rate is maximized. The heat transfer across the fins is by laminar forced convection bathed ...
-
Bello-Ochende, Tunde; Meyer, Josua P.; Ogunronbi, O.I. (Elsevier, 2011)This work describes the effect of steady-state laminar forced convection on multiscale rotating cylinders in cross-flow. The objective was to numerically maximise the heat-transfer-rate-density from the multiscale cylinder ...

Meyer, Josua P.; Olakoyejo, O.T. (Olabode Thomas); Bello-Ochende, Tunde (Elsevier, 2012-10)This paper presents the development of the three-dimensional flow architecture of conjugate cooling channels in forced convection with internal heat generation within a solid. Two types of cross-section channel geometries ...

Lorente, S.; Cetkin, E.; Bello-Ochende, Tunde; Meyer, Josua P.; Bejan, A. (Elsevier, 2012-09)Here we show theoretically that swimming animals and athletes gain an advantage in force and speed by spreading their fingers and toes optimally. The spacing between fingers must betwice the thickness of the boundary ...

Design and optimization of a downhole coaxial heat exchanger for an enhanced geothermal system (EGS) Yekoladio, Peni Junior; Bello-Ochende, Tunde; Meyer, Josua P. (Elsevier, 2013)The present study considers the design, performance analysis and optimization of a downhole coaxial heat exchanger for an enhanced geothermal system (EGS). The optimum mass flow rate of the geothermal fluid for minimum ...

Le Roux, Willem Gabriel; Bello-Ochende, Tunde; Meyer, Josua P. (Elsevier, 2014-08)The first law and second law efficiencies are determined for a stainless steel closed-tube open rectangular cavity solar receiver. It is to be used in a small-scale solar thermal Brayton cycle using a micro-turbine with ...

Mwesigye, Aggrey; Bello-Ochende, Tunde; Meyer, Josua P. (Elsevier, 2014-12)In this paper, a numerical investigation of thermal and thermodynamic performance of a receiver for a parabolic trough solar collector with perforated plate inserts is presented. The analysis was carried out for different ...

Olakoyejo, O.T. (Olabode Thomas); Bello-Ochende, Tunde; Meyer, Josua P. (Elsevier, 2012-04)This paper presents a three-dimensional geometric optimisation of cooling channels in forced convection of a vascularised material with the localised self-cooling property subjected to a heat flux. A square configuration was ...

Obayopo, Surajudeen Olanrewaju; Bello-Ochende, Tunde; Meyer, Josua P. (Elsevier, 2012-07)A proton exchange membrane (PEM) fuel cell has many distinctive features which make it an attractive alternative clean energy source. Some of those features are low start-up, high power density, high efficiency and remote ...
